Patent GB-824596-A (GB)
Title: Improvements in or relating to the separation of hydrocarbons using molecular sieves
IPC: C07C7/13
Filed: 1958-02-12
Abstract: In a process for separating hydrocarbons by means of a molecular sieve in an adsorption zone, the hydrocarbon mixture is first passed through a pretreating zone containing a molecular sieve of the same pore size as that in the subsequent adsorption zone, such pretreatment being performed at a temperature at least 50 DEG  F. below that employed in the adsorption zone.  In the separation of normal paraffins from other hydrocarbons a 5 \fa molecular sieve is used in both pretreatment and adsorption zones, the pretreatment being performed at below 150 DEG  F. and preferably in the liquid phase at ambient temperatures and the adsorption being performed, preferably in the vapour phase, at 200-400 DEG  F. In an example the weight ratio of sieve in the pretreatment zone to that in the adsorption zone was 0.66:1.  Normal hydrocarbons adsorbed on the main sieve are periodically desorbed, e.g. when the sieve is saturated, by conventional means such as by the use of a desorbing gas, e.g. an olefine, preferably propylene, by increasing the temperature and/or reducing the pressure, or by a heated inert gas purge, e.g. nitrogen or oxygen -free flue gas. The main sieve may also occasionally be regenerated by burning off deposits with a dilute oxygen-containing gas.  The pretreatment sieve is also periodically regenerated; in an example using a complete cycle (adsorption and desorption) of the main sieve lasting three hours, the pretreatment sieve was regenerated every 50 cycles by heating to 800 DEG  F. and lowering the pressure to 4 mm. mercury.  Other methods of regeneration can be used such as burning or using a hot inert purge gas.  Feed rates should be low, preferably below 4 wt./wt./hr., and the feed should be dried before pretreating.  Reference is also made to the separation of aromatic hydrocarbons with a 13 \fa sieve.

[Also in Group XXIX] In an hydraulically operated forging press having a vertical operating chamber 10 within which a piston 13 connected to the tup is forced downwardly by hydraulic fluid which is cut off before completion of the downstroke to allow the stroke to be completed by momentum, anti-cavitation means 22 are incorporated in the cylinder to ensure that the fluid is maintained in contact with the piston when the supply has been cut off. The piston operates in an inner sleeve 12 spaced from the bore of the chamber 10 to provide an annular space 16 communicating through ports 20, 21 with the interior of the sleeve. The space 16 contains a flexible sleeve 22 of synthetic rubber surrounding a metal carrier cylinder 23 and clamped thereto at its opposite ends by rings 31, 32, 33. U-packings 34 and ring seals 26, 27 prevent leakage of fluid. One or more atmosphere valves 48 are provided externally of the sleeve 23. When the piston 13 is under pressure the sleeve 22 is pressed against the inner wall of the chamber 10 and closes the valve 48 on its seat. Upon the fluid supply being cut off the continuing movement of the piston draws the flexible sleeve 22 against its carrier cylinder permitting the valve 48 to be opened by a spring 49 and thus maintaining the hydraulic fluid in contact with the piston. The valve or valves 48 may be omitted and the wall of the chamber 10 perforated with small holes, in this case the sleeve 22 may be reinforced locally to prevent it being forced through the holes when under internal pressure. Specification 798,748 is referred to.
